TH RO TTLE-VALVE LEVER.

SPECIFICATION forming part of Letters Patent No. 470,494, dated March 8,1892.

Application filed July 8, 1891. Serial No- 398,791. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK W. KLINE, a

citizen of the United States, and a resident of North Germantown, in thecounty of Columbia and State of New York, have invented certain new anduseful Improvements in Throttle-Valve Levers, of which the following isa specification.

The object of my present invention is to provide a simple and efficientthrottle-valve lever; and it consists of a lever having a handle jointedthereto, and on one side of the lever a sliding bar provided with teethwhich engage with a curved serrated arm, and this sliding bar' has onits outer end a head which engages with the inner end of the hingedhandle, whereby the sliding bar or latch at the initial movement of thehandle in either direction will move the latch inwardly and causeitsinner toothed end to disengage from the curved serrated bar, and themoment the hand is removed from the handle the spring will throw backthehandle and cause the teeth to engage and hold the lever in the positionto which it was moved, as will now be set forth in detail.

In the accompanying drawings, Figure 1 is a front view of my improvedthrottle-valve lever; Fig. 2, a view of the under side; Fig. 3, a viewof a portion of the under side enlarged and partially cut away in thehandle to show construction, and Fig. 4 a front or edge View of samewith portion of the handle cut away.

In constructing my invention I hinge the inner end of the lever A to theusual links B, attached to a stationary object, and make the ordinaryconnection to the valve by means of the connecting-rod C.

To the outer end of the lever A, I hinge a handle D, so that it iscapable of a slight swinging motion back and forth on the pivotpin E. Onthe under side of this lever I place three keepers F G H to receive asliding bar or latch I. The outer end of this latch has a diverging headJ, which rests against the inner end of the handle D, and on the slidinglatch I, inside of the first keeper F, is a collar J, between whichcollar and the middle keeper G is a coiled spring L to hold thelatch-head J in contact with the hinged handle D.

Between the keepers G H the latch I has a cut-away or gained portion Mon the side facing the lever A, through which the serrated segment Npasses. The lever thus constructed is capable of various modifications,such as making the lever A tubular and inclosing the latch and springinside; but in such a case the handle D would be hinged thereto in themanner here shown substantially and the other parts would be constructedthe same as shown herein in principle, although differing somewhat indetails.

In operation the engineer grasps the handle D and moves it forward orbackward. In doing so the initial movement turns the handle to theposition indicated in dotted lines 0, Fig. 3. As a result, the contactedge of the inner end of the handle throws in the latch I, causing theteeth of the latch to be disengaged from the serrated edge of thesegment N. The nextmovemcnt of the hand moves the lever Aitself, andwhen the proper throw of the lever is obtained the initial motion ofreleasing the handle causes the spring L to act and thus return thehandle to its normal position, as shown in Figs. 2 and 3.

What I claim as new is- 1. A throttle-valve lever composed of a leverwith a handle hinged thereto at its outer end, a longitudinally-movablelatch on one side with a flaring headengaging with the inner end of thehinged handle, a spring for holdingthe latch in contact with the hingedhandle, and a serrated segment engaging with the toothed end of thelatch, substantially as set forth.

2. A throttle-valve lever composed of a lever with a handle hingedthereto at its other end, in combination with a longitudi fillymovablelatch slidingin keepers on'one side, withthe flaring head engaging thehandle, a spring for holding said latch in contact with the handle, aserrated segment engaging with the toothed end of the latch, and a rodfor connecting said lever with the operatingvalve, substantially as setforth.

Signed at North Germantown, in the county of Columbia and State of NewYork, this 2d day of July, A. D. 1891.
